ClSTERN-CLEANER AND WATER-PURIFIER.

SPECIFICATION forming part of Letters Patent No. 784,583, dated March14, 1905.

i Application filed July 7, 1904. SBIIZLINO. 215,667.

To (Ll Z whom it may concern.-

Be it known that I, THOMAS S. MURRAY, a citizen of the United States,residing at Arkansas City, in the county of Cowley and State of Kansas,have invented a new and useful Improvement in Cistern-Cleaners and ater-Puriliers, of which the following is a specification.

This invention has for its object a device for cleaning cisterns andpurifying the water therein by means of a simple appliance adapted to beeasily rolled upon the bottom of the cistern, removing the sedimenttherefrom and purifying the water therein.

A furtherobject of the invention is to separate the water and thesediment, and the filtration, aeration, and consequent purification ofthe water, and the return of the same to the cistern or to some otherreceptacle, whereby the cistern is cleansed without waste of the watertherein.

IVith these objects in view the invention consists in the novel featuresof construction and combination of parts hereinafter described,particularly pointed out in the claims, and shown in the accompanyingdrawings, in which Figure 1 is a perspective view of my device complete.Fig. 2 is a detail vertical section through the brush-easing and thecylinder, parts being in elevation. Fig. 3 is a detail sectional view ofthe handle portion. Fig. 4 is asection through the handle on the line44; of Fig. 1. Fig. 5 is a section through the brush-containing casingand the cylinder at right angles to the section shown in Fig. 2. Fig. 6is a plan view of the casing shown in Fig. 5. Fig. 7 is a detailperspective view of one side and corner of the casing, showinginperspective the parts carried thereby. Fig. 8 is a side elevation of theparts shown in perspective in Fig. 7, parts being shown in section. Fig.9 is a detail sectional view through the dischargepipe and air-chamber.Fig. 10 is a detail sectional view of the packing around the lower edgeof the casing. Figs. 11 and 12 are detail views, partly in section,illustrating a clutch mechanism. 13 is a (letail view, partly insection, of the upper end portion of a cylinder, puppet-valves beingshown in elevation.

In constructing the device I employ a downwardly-open casing A, mountedon wheels A, and in the casing are arranged shafts B, having at one endand exterior of the casing sprocket-wheels B. WVithin the casing theshafts B carry brushes B adapted to rotate in opposite directions, aswill hereinafter appear. Mounted upon the casing and journaled insuitable brackets is a shaft C, cranked as at C, and a yoke C of ahandle C is mounted on the shaft C, the shaft passing loosely throughthe end portions of the yoke. The handle or pole C may be of any desiredlength and for use with deep cisterns may be formed in sections jointedor otherwise detachably connected. Adjacent its upper end the handle Ccarries a sleeve I), which extends upon each side of the handle and hasbearings formed thereon, and on one of these bearings is journaled apulley I)", and adjacent the pulley the sleeve D carries ahorizontally-extending handle or handheld D and on the opposite side ofthe pole C the sleeve carriesa sprocket-wheel D adapted to be actuatedby a crank-handle D". Above the sleeve the pole C has eyes E and Esecured therein, the eye E being of greater diameterthan the eye E. Thecasing A has an opening formed in its top, over which is arranged asocket F, having an opening alining with that in the casing, theopenings being closed normally by an upwardly-opening valve F, and acylinder F has its lower end threaded into the socket F. In the cylinderF works a plunger F, having connected thereto an upwardly-extendingplunger-rod F. The cylinder F -is arranged adjacent one end of thecasing A, and adjacent the opposite end is pivoted a lever Cr, having anintermediate slotted portion G, through which extends the crankedportion of the shaft C, and the forward end of the lever Cr carries apreferably integral segment (1, and to the ends of the segment arepivoted the ends of a bail G, the bow portion of the bail beingconnected to the upper end of the plunger-rod F". From the side of thecylinder adjacent its lower end extends a dischargepipe H,

which extends upwardly, being passed through and supported by the eye E.The lower portion of the discharge-pipe may be of metal with hoseconnection, and the metal portion carries a laterally-extendingcylindrical air- ,chamber H, communicating with the discharge-pipe H andin the pipe H adjacent the air-chamber, and between the air-chamber andthe casing or lower end of the discharge-pipe is arranged a flap-valve Hadapted to permit discharge of sediment from the casing A, butpreventing its return. On the top of the casing is arranged horizontallya perforated pipe-section J, and a flexible tube J extends from an endof the pipe-section to the top of the cylinder F and is connected to'anipple J carried by and opening downwardly into the cylinder. From thetop of the cylinder F there also extends an air-pipe J carried by theeyes E, placed on the handle 0", the lower end of the pipe J beingconnected to a nipple J*, also carried by the top of tlie cylinder F Thenipples J and J are provided with a commonform of puppet-valve J", thesaid valves being oppositely acting, whereby air is admitted into thecylinder F through the pipe J 2 and nipple J and discharged from thecylinder through the nipple J and pipes J and J. Sprocket-wheels K and Kare carried by the shaft 0, and a sprocket-chain L runs over thesprocket-wheels D and K. A sprocket-chain M runs over the sprocketwheelsK and B and over an idler M, the object of the idler being to hold thechain M in engagement with the rear sprocket-wheel B, the chain runningover the wheels B, so as to rotate them in opposite directions.

To actuate the traction-wheels and move the casing A over the bottom ofthe cistern, the shaft A projects onone side and carries a gear-wheel N,which meshes with a wormgear N, the upper end of the worm-gear shaftcarrying a pinion N and being journaled in bearing carried by a yoke O.The shaft 0 carries gears P, adapted to be engaged by the pinion N Theyoke O is secured to a collar 0, sliding on the shaft (1, and the yokealso carries a laterally-extending arm 0 having rollers O mountedthereon. A cam-lever Q is pivotally mounted on the shaft C, the cam edgeof the lever working between the rollers O As the lever is shiftedbackward and forward the pinion N is caused to mesh with one or theother of the gears P, thereby causing the casing to move backward orforward,

as may be desired.

- The lower end of the worm-gear is journaled in a pivoted lever B. Aspring Sis connected at one end to the arm of the lever B and at theopposite end toan eccentric S. A red S is connected at one end to theeccentric, and a cable S extends from the free end of the rod S Thecam-lever Q is actuated by a double cable Q, connected to the-free endof the cam-lever and running overa pulley Q A pull on one of thecables'Q moves the lever Q in one direction, and a pull on the othercable Q moves the lever in the opposite direction. A pull on the cable Slifts the worm-gear out of engagement with the gearwheel N. r

A strip of leather or other suitable packing is run along the lower edgeof the casing, as shown at T, and is held down by a sack T, carried bythe lower edges of the casing and weighted with shot, limiting theinflow of water to an amount suflicient to thin the sediment to bepumped out. Within the receptacle is pivoted at the rear end areceptacle U,

held in place by a hook U and having a screen U forming its front end,the object of the receptacle being to catch and hold any large objectswhich might clog the valves of the discharge pipe or cylinder. By meansof this device the bottom of the cistern or of any reservoir or tank maybe run over and scoured, the water being aerated, the sediment pumpedout, and objects too large to pass through the hose will be thrown bythe rear brush intothe receptacle U and held there until the casing hasbeen lifted from the cistern or tank.

'I therefore pump out but a small portion of water to clear and purify acistern a very' desirable thing during drought or when the supply ofwater is limited. J

The introduction of air into the water freshens it and gives it life,rendering it more palatable than water which has been standingundisturbed for a considerable length of time.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is
